So im in a bit of a hard spot with my 94 v6. I got the v6 in hopes of getting decent fuel economy, well unfortunatly im getting around 14.6 consistently. I thought id do a tune up on it in hopes of improving the mpgs so i spent 90 bucks on new plugs and wires only to be dissapointed once again when i found no gains in mpgs. The car is bone stock aside from a divorced dual exhaust. I am not running any rear o2 sensors because from my understanding they are there only to monitor if the cats are filtering, and since i have no cats i didnt feel the need to have them. I have thought about putting some in but i dont want to drop another 150 bucks on something thats not going to help. Im not expecting much better but at least 19mpg would be nice. Most of my driving is on rural roads going about 45-50 mph with little stops. I very rarely "get into it" with what little power it has. Im starting to get sick of it and am about to yank the v6 out and drop in a 302 at least ill have a little bit of power to go along with my crappy gas milage. Any advice to me on how to improve my gas milage. Oh btw the car only has 110,000 miles on it.
